Application filed January To all whom it mayv concern: 7

Be it known that we, Jnssn FULnNwInnR, and HARRY FULnNwIDnn, citizens of the United States, residing at Savannah, in the county of Chatham and Stateof Georgia, have invented new and useful Improvements in Roofing Fasteners, of which the following is a specification.

This invention relates to roofing fasteners and particularly to that type of device which is used for holding in place composition shingles when laid diamond-wise.

The principal object of the invention is to provide a'roofing fastener which will allow for thermal expansion of the shingles.

Another object of the invention is the provision of a roofing fastener. having means which co-act with the edges of a shingle in the previously laid row of shingles for allocating the roofing fastener in proper position to receive a shingle of the row being laid.

Other objects of the invention will appear in the course of development of the following description and claims.

In the drawings Figure 1 is a plan View showing a portion of the roof including overlapped shingles held in place by the device of our invention.

Figure 2 is a plan view of one of the roofing fasteners.

Figure 3 is an end elevation.

Figure 4 is a perspective view of one of the roofing fasteners.

Referring now in detail tow the several figures, the numeral 1 designates shingles in a basic row. The roofing fasteners are used in pairs, rights and lefts as indicated'at 2 and 3 in Figure 1 each of which fasteners consists of substantially a flat plate 4; having allocating flanges 5 and 6 struck up on two adjacent edges of said plate on one side thereof, and a troughdike flange. 7 formed on one of the remaining edges of said plate on the other side thereof and preferably extended longitudinally at one or both ends as indicated at 8 so as to present a relatively extensive engaging surface to the support of the shingle which is to he received by said trough-like flange, thereby preventing binding and buckling of the shingle, such as takes place when relatively narrow flanges are used.

In the illustrative embodiment of our invention a preformed nail hole 9 shown by 21, 1925.: SerialNo. 3,799.

means of-which the, roofing fastener is se- I cured in place, but, ifidesired the roofing fastener may be made without the nail hole and-the latter formed by drivinga nail througlrthe imperforate plate.

In the operation of using" our improved roofing fastener, a pair of them, one right and one left are allocated by placing the flanges 5 and 6 against the edges which form ,the corners of adjacent shingles of a row already laid, this being clearly indicated in Figure 1. The trough-like flanges? are thenin proper position to receive the corner ofthe overlying shingle. The roofing fasteners are secured in place by driving a nail through the plate 4, corners of the adjacent shingles of the previously laid row and into the sheathing of the roof. The overlying shingle is then laid in place with the edges which form its lower corner seated within the trough-like flanges 7. The latter are preferably made wider than the thickness of the shingle so as to provide ample drainage and quick evaporation of moisture from said trough-like flanges.

Roofing fasteners have heretofore beenv made with the pair of trouglrlike flanges formed on a single plate. These have had the drawback of causing the shingle to buckle in thermal expansion by reason of its being confined within the trough-like flanges which are rigidly related and the distance between which cannot vary. In the present device the right and left troughlike flanges are formed on separate pieces and there is sufficient strain that is to say, movement between the roofing fastener and its connection with the roof to permit the slight amount of relative elongation between the right and left trough-like flanges to take care of the lateral expansion of that porbetween the roofing fastener and the roof permits a slight pivotal motion of the roofing fastener so that it swings enough to accommodate the change in position of the edge of the shingle "under expansion, this pivotal movement being compounded with the slight give between the roofing fastener and its connection with the roof above referred'to. It is to be understood that the actual amount of diversion in the direction of the edge of the shingle due to expansion is extremely slight and that there is always suflicient play between the allocating flanges 5 and 6 and the edges of the shingle with which. they co-act, to permit the roofing fastener fully toperform itsfunction.

While we have above described what we believe to be a simple and practical embodiment of the invention it isto beiunderstood that certain changes ora lterations in the construction may be resorted to if desired without departing from the spirit and scope of the invention as claimed.

Havingde'soribed ourinve'ntion what we elaim as new and desire to secure by Letters Pate t, is 1-"- j 1. In a roofing fastener, a pair ofplates each formedwith means for supporting an each plate being formed with a trough-like shingle supporting flange upturned on the opposite side'of said plate, said plates being adapted for pivotal mounting upon a roof in superposed relation to a previously laid row of shingles, in right and left jux'ta position with their shingle supporting means oonfrontlng and the upturned edges in substantial contact with the ad acent corners of a pair of adjacent shi-ng'le's in the ,pre-

viously' laid row.

In testimony whereof we have hereunto setiour hands. V V
